Sessions were silently dying and losing chat history because:
- Pipe write errors (EPIPE) were completely undetected — broken pipe
writes via Task.detached { handle.write() } failed silently, leaving
the app unaware the subprocess had crashed
- Reconnection fell back to newSession() when loadSession() failed,
creating a blank session and permanently losing all conversation context
- No message reconciliation after reconnect — DB-persisted messages
were never re-fetched, so the UI stayed stale/incomplete
- Keepalive sent bare "\n" which caused json.loads("") parse errors
in the ACP library every 30 seconds, destabilizing the connection
- TERM=xterm-256color was set on a pipe-based subprocess, risking
terminal escape sequence pollution in the JSON-RPC stream
Fixes:
- Replace FileHandle.write() with POSIX Darwin.write() + SIGPIPE
suppression for immediate broken-pipe detection at all write sites
- Send valid JSON-RPC notification {"jsonrpc":"2.0","method":"$/ping"}
as keepalive instead of bare newlines
- Never fall back to newSession() during reconnection — try
resumeSession then loadSession, fail visibly if both fail
- Add reconcileWithDB() to merge DB-persisted messages with local
state after successful reconnection
- Finalize streaming messages immediately on disconnect so partial
content is preserved before reconnection begins
- Use SIGINT instead of SIGTERM for graceful Python subprocess shutdown
- Remove TERM env var from ACP subprocess environment
- Consolidate disconnect cleanup into single idempotent method
- Add isHandlingDisconnect guard against double-handling
- Increase reconnect attempts from 3 to 5 with capped backoff
- Add "Reconnect" button to toolbar error state
Also: bump version to 1.5.1, set deployment target to macOS 14.6
(Sonoma), and update README with rich chat/ACP features, process
controls, skill editing, and corrected system requirements.

Dashboards with a webview widget now show a tab bar: Dashboard tab
renders all normal widgets, Site tab displays the web content
full-canvas with even margins. Cleaner UX than the split layout.

New widget type that renders any URL (local dev servers, HTML reports)
directly in the dashboard via WKWebView. Sections with webviews
automatically split layout: grid widgets left, webview right.
Configurable height, non-persistent data store, navigation error logging.

Hermes cost tracking returns $0.00 for models not in its static
pricing table (including claude-haiku-4-5). Token counts remain
displayed since those are always accurate.
